Unfortunatly, Merry didn't see the horn of Gondor tied to Boromir, banged into it, and passed out.
---or---
Aragorn: Wait a minute...why aren't the orcs chasing us anymore?
Legolas: I feel like we're not in Rivendell anymore
Boromir: Thank you captain obvious!
Merry: Where is Frodo?
Pippin: Where is Sam?
Everyone: Where's Gimli?!?
***meanwhile, back at the orcs***
Gimli: Ok, here's how it will work. Now, you come at me, and i'll hit you, and then you come at me and i'll hit you, and then you come at me and i'll hit you. Any questions?
Orcs: um....truce?
